Apparently you have very little experience with warriors or those who play them at a high level.
The stance dancing change, from all available sources in lieu of an actual player pool with normal distribution, has been overwhelmingly canned by players, and actually is against Blizzard's stated goal of "meaningful decisions". Stances currently have a meaningful impact on performance; there are specific instances where being in a particular stance is beneficial. In contrast tying ability availability to stances does absolutely nothing to gameplay except introduce more macros. This is the whole reason stance dancing was removed in the first place; it requires macros and unfairly punishes those with higher latency. Nothing more irritating that having that polymorph land because you couldn't get your spell reflect macro to activate fast enough. I haven't seen a single player provide a convincing argument on why ability stance dancing is a good thing. The ability to write functional macros, most of which require you to visit a website (and which is definitely something Blizzard has been trying to distance itself from) isn't skill, and neither is living in a location where you get sub 50ms latency at all times.
I get that they want to stances to feel different and be meaningful, but the current version of stances does that far better than what they are doing in Beta. It is the fact that the implementation of stances is doing exactly the opposite of what they intend that gets me. This isn't a situation where they don't like the feel of a spec (i.e fury) and want it to feel more "furious". It is a situation where they are trying to implement a change that in reality does exactly the opposite of their intentions, and that they are completely disregarding all the feedback telling them so because, "trust us, you will like this change".
